Girlfriend had to choose between me and her family And she broke up with me?

I'm devasted because we were going to move out and I really thought she was the one. Her mom said she would never speak to her again. she broke it off and Im literally just in a state of shock. I'm numb. Should I give this time or seek professional help. I really don't how I'm going to get over this. How long does it take.

Updates:

She called me the next day balling and crying saying she made a mistake I told her to make a choice and stick with it.

It doesn't matter. How many times does everything look perfect and then next thing you know you're broken up. It's a hard decision for her to make. She's left with nothing if you break up with her. What's up with you and her family? That's important info.
